Hello, I am currently working on a project using the Omnivision OV6620 CMOS color image sensor (the same one used by the CMUcam). I have the OV6620 interfaced to an Atmel AVR microcontroller, and I am able to extract images from the camera and display them on a PC (through a PC app I wrote...the images get sent up over the serial port). Anyway...my question has to do with the Bayer image ...

Hello experts, For a new project, I am considering the AT91 series of ARM processors from Atmel. Anybody here have experience with these processors, and the tools? I know the "which compiler is best" is a very "religionbased" question, but nevertheless I'll give it a shot. So, in your opinion, which tools is worth a look, and which is NOT? Thanking you in advance. Best regards H...

Does anyone know the lowest cost microcontroller with a USB interface? I have done some Googling, and it seems there are quite a few USB microcontrollers based on either ARM or 8051. Either is okay, but they are not very cheap. They are all over $3 @ qty 1000. The cheapest I have found so far is the Atmel AT90USB82, which is an AVR. It is just under $2 @ qty 1000. Here is what I nee...

Hi Is it just me or does anyone else think that Microchips latest move (removing Microchip FAEs from distributers), is another big mistake? Already my companys biggest distributer has decided to stop pushing Microchip (because they can no longer provide the full support package), in favor of Atmel. I know that Microchip think that providing all an FAEs function using their new onli...

Hi - I'm currently using an Atmel AT91SAM7X256 to do a large amount of floating point operations (mostly multiplies with a decent amount of trig as well). It does OK - but my floating point needs are soon going to be expanding (by about twenty-fold) and I'm starting to worry that the SAM7X part just won't have enough horsepower for this. I thought about going with a DSP - but then the idea ...

Hi! I'm trying to have the BasicGraphicDisplay sample (provided on Atmel C with the eval board) working on my board. I believe some of the example provided with the board only apply to the DK, not the EK. But since al the hardware is here (clock generator and display controller), this on should work. When I ran the program, I received this message : "ICS1523 Clock Generator Init failed"...

hello, well my problem is that i have a jtagice mk1 and i would like to use the jtag feature for programming more than what it states it works with could someone advise me if the winarm project would support this programming device for more micros so it can be possible to program more of the atmel family of micro controllers ie. arm family of 32bit micros. my thought was that all the micros ...

Hello there. I´m new working with microcontroller, at the moment never try using USB. I´planning to develop a interface PC-USB proyect (using atmel ATMEGA16), where a infrared-led acts as a light analog sensor, depending on the leght of hte light disturbance the microcontroler has to distinguish between two posible paths, i was thinking on sending this signal to a PC-host software where the ...

I'm trying to use the Synchronous Serial Controller (SSC) on the Atme AT91SAM7S64 development kit (AT91SAM7S-EK) to interface with a Nordi nRF2401 radio transceiver. The Atmel documentatio (6175A-ATARM-13-Jul-05, page 352) indicates that the SSC's transmit cloc can "drive the TK I/O pad continuously or be limited to the actual dat transfer." However, the options for controlling the output o...

I am looking for a PIC or Atmel Micro that has 4-independentl controlled PWM channels of about 10-bit resolution . The frequnenc can be the same but I need simultaneous 0-100% duty cycle control o each channel independently . The max PWM frequncy should be greate than 1KH Price Range $2.00-$6.00/usd. A few A/D channels, interrupts,C-Compile friendly. I have looked @ the PIC18F1220, however ,...

http://www.indiegogo.com/projects/iteaduino-lite-most-inexpensive-full-sized-arduino-derivative- board At first I was presently surprised but after a while I started to wonder. Knowing that the cheapest AVR device costs about $3-$5 I started to investigate how they could build a complete board with MPU for $5 including shipping. It turns out the Chinese have CLONED the Atmel AVR process

Hello, we are designing a microcomputer named "Comet" based on the Atmel AT91RM9200 controller. All design files and software will be licensed under the GPL. Currently the schematics is all what we have. We probably packed too much building blocks into the design. Before we cut down the design and start building the PCB it would be nice to hear what you think which optional building blo...

Hi, I've recently started development with a Philips LPC2103. I know Atmel has a site, AT91.com, which I found useful for AT91SAM stuff. I'm looking for suggestions or recommendations on websites/forums that discuss using the LPC21xx parts. I did the Google search already but ended up at sites that archive "the real" forums. If it makes a difference, I'm planning on using the ...

Hello all again, Let me tell you in brief about this. We are developing a USB device(having AT91SAM7) which has a control and two Isochronous endpoints(1 for IN & 1 for OUT) and a bulk endpoint. The device is a custom type device. It sends and receives packets on Isochronous endpoints once enumerated. Now we are using ATM6124.sys driver provided by ATMEL for their Evalu...

Hi, Maybe it sounds stupid, but I?m new to NXP. I have always been using atmel. I?m working now with the OLIMEX LPC2379STK from IAR systems. I?m using IAR embedded work bench and I try the sample codes and the work. But what I don?t understand is that when I?m writing my code identical to the sample code it just won?t work. For example: void InitClock(void) { // 1. Init

I've got an SPI master/slave test circuit set up between two Atmel ATmega8 microcontrollers, with the master on an STK500 development board and the slave on a breadboard. I noticed that sometimes I would get noisy communications and other times I would not get any noise at all, but it seems to depend on how the wires are positioned. The cables I'm using to connect master and slave are some "ran...

Friends, I am a newbie to the world of embedded systems. So please bear to read this long message. I have a at91sam9261ek in which I have successfully ported u-boot and linux (after compiling their source code which I have downloaded from Linux Link by TimeSys). Now i wish to connect a smart card (ISO 7816) to it. From the atmel documentation, I understand that I have to connect it using USA...

I have a board based on the AT91RM9200, and want to boot from SPI dataflash. The loader will proceed to boot u-boot (Which is too big for the ROM bootloader to handle). I have read the atmel appnote on that, but boot program will need to be changed. My SDRAM is configured differently than the DK. The program with the appnote includes source, but it is missing quite a bit to be able to be ...

Hi, does anyone know how fast an ARM processor, specifically Atmel's AT91SAM9261 can bit-bang its general-purpose ports? I'm trying to get speeds on the order of 3-6 MHz at a minimum. The idea is to write to a DAC, turn the direction of the 16-bit "bus" around, read from an ADC, and repeat. Thanks!
